Hepatic portal venous gas associated with transcathete cardiac defibrillator implantation: A case report.

INTRODUCTION: Hepatic Portal Venous Gas (HPVG) is a rare pathological condition that may be caused by iatrogenic factors.

CASE REPORT: A 66-year-old Chinese male patient with HPVG underwent laparotomy for chronic bowel ischemia. Transcathete cardiac defibrillator was implanted via left subclavian vein for ventricular tachycardia.

DISCUSSION: There are many hypotheses about how gas runs through the intestine into the mesenteric portal venous system. HPVG patients can be improved through comprehensive management. Patients with mesenteric ischemia should be observed in hospital and after discharge, and need surgical intervention if chronic bowel ischemia recurs.

CONCLUSION: This case proves the usefulness of comprehensive management in treating HPVG. Prognosis of HPVG should consider the pathological changes contributing to HPVG.
